Account

The witness and a visiting companion were awakened in the home in the middle of the night by a loud unnatural howling that seemed to pass the house and fade into the distance over about ten seconds. They stayed inside and assumed at the time it was dogs or coyotes. The witness later shared the account after reading similar descriptions while still doubting it was Bigfoot-related.
